不打扰是莪最后的温柔 提交于 2020-06-28 04:42:18
问题 I'm kinda confused about unicode characters codepoints conversion to UTF-16 and I'm looking for someone who can explain it to me in the easiest way possible. For characters like "𐒌" we get; d801dc8c --> UTF-16 0001048c --> UTF-32 f090928c --> UTF-8 66700 --> Decimal Value So, UTF-16 hexadecimal value converts to " 11011000 00000001 11011100 10001100 " which is " 3624000652 " in decimal value, so my question is how do we got this value in hexadecimal?? and how can we convert it back to the

Jetty 9, character encoding UTF-8

问题 I have a problem with encoding and Jetty. All my files are encoded in UTF-8 and include the correct HTML meta tag to specify UTF-8. Until now all my UTF-8 files had a BOM and I had no problem. But now I am using a different text editor and I noticed that my UTF-8 files are now generated without a BOM which from what I read is rather a good thing so I decided to go without BOM from now. But the problem is that it seems that Jetty converts all my JSP files to ISO8859-1 before sending them to
